The distance between the ships is 26.65.
<h3>How to illustrate the distance?</h3>
Based on the information given, after 3 hours, the distance of ship B will be:
= 20 + (17 × 3)
= 71.
A = 21 × 3 = 63
Well calculate the square root which will be:
A² + B² = 71² + 63²
= 5041 + 3969
= 9010
Therefore, ✓9010 = 94.92
Finally, the distance will be:
= (63 × 21) + (71 × 17) / 94.92
= (1323 + 1207)/94.92
= 26.65
